Did those come in different sizes and grits???
For the cable stop removal I used a Dremel to grind down the spot weld dimples, then vice grips to yank the brackets, then more Dremel action on the weld scabs, then hand filed the last mm, then sanded. Each one took about 40 minutes because as you know, you gotta be REALLY careful when you get close.
For all the slag removal and ugly weld cleanup I used steel brush wheels, the Dremel, files, steel wool, whatever would fit in the nooks and crannies. The BB cluster was a mess of rough scabs and slop. Nasty.
So far, all these old Schwinns I have worked on have been impressively straight, but the attention to cosmetic detail is nonexistent.
Today I am going to clean up the head tube cluster. Where they rolled and stretched and formed the "Tube" the steel exhibits "stretch mark" types of scars in the contours of the Faux Filet Braze area. It's really noticeable and I can't believe they sold the bikes with translucent paints. Totally obvious and ugly.
